Hi, all,
Does anybody know what the intracranial volume and supratentorial volume include? Does it include only the parenquima volume (white matter / gray matter volumes) or it includes the ventricules and CSF?
What about the WM hhypointensities? Are they included in the WM Volume measurement or in the intracranial volume?

Hi Bruce:
Following up on Carolina's question, if I understand correctly,
Is ICV = GM+WM+Ventricular Volume ?
and
Supratentorial Volume = GM+WM ?
thanks,
Alan

Hi Alan
the ICV we compute is from the det of the talairach xform using Randy Buckner's method (see his paper on this topic). It includes everything inside the skull implicitly.
I'll leave Supratentorial for someone else, as I don't remember.

btw, the intracranial volume is an estimate based on the talairach transform (it is not computed by counting voxels in the cranium). doug
